Calculate the total hours and minutes between a start time and end time, including overnight shifts that cross midnight.
This tool calculates the exact duration between a start and end time, useful for tracking work hours, shifts, or any time span.
The tool converts both times to minutes since midnight, subtracts them, and if the result is negative, assumes the end time is on the following day (overnight shift).
Enter your start time and end time, then click Calculate to see the total duration in hours, minutes, and decimal format.
Example: A shift from 9:00 AM to 5:30 PM totals 8 hours and 30 minutes, or 8.5 decimal hours.
Does this handle overnight shifts. Yes, if the end time is earlier than the start time, the tool assumes it crosses into the next day.
Why is decimal format useful. Decimal hours are often used for payroll calculations, since 8.5 hours is easier to multiply by an hourly rate than 8 hours 30 minutes.
